Both main characters possess unique traits that make them desirable. Because of that, they're sold off to the prince to marry. Each girl has a strong personality and a kind heart that will change the princess nasty behavior to a good person. Lots of romance, shoujo, fantasy anime. Definitely a breath of fresh air than all these isekai romances
